Wondering how fast the RX1R II focus tracking and shutter speed is? This fast…tiny bubbles on waves in a reef tide pool. I’d seen the demos of the A7R II at a trade show, shot Formula One with one too, but hadn’t shot or tracked any action yet with the RX1R II as we previously shared, David did with his demo at a skatepark. Well, that was impressive and a totally in-the-moment, walking on a beach shot.
